Glass fiber needle felt is a reasonable structure, better performance of the filter material to fiberglass as raw material, with a needle on the comb after the chopped fiberglass felt for acupuncture, mechanical method to make between the fiberglass, Felt-like non-woven fabric filter material made of fiberglass and reinforced fiberglass webs which are entangled with each other and the web is reinforced.
It has the advantages of high temperature resistance, corrosion resistance, dimensional stability, elongation shrinkage rate and high strength, and the felt fiber is single fiber, three-dimensional microporous structure, high porosity, little resistance to gas filtration, Is a high speed, high efficiency and high temperature filter material. Compared with other high temperature chemical fiber mat, it has the advantages of low price, higher temperature and other special advantages, but its running resistance is higher than the general chemical fiber high temperature filter.
1, good heat insulation: According to the physical principle, the thermal conductivity of the gas is small, excellent heat insulation material inside a lot of air holes. The glass fiber needle cotton has numerous fine gas, and the fiber is irregular arrangement, for the excellent insulation material, thermal conductivity of 0.2 ~ 0.040kcal / mhr. C between;
2, will not burn: the main component of glass fiber silicide (accounting for more than 50%), with non-flammable, no deformation, no embrittlement, high temperature of 700 ℃;
3, sound absorption is good: when the sound wave into the glass fiber cotton, the energy will be different from the fiber and the size of the cavitation of friction, and was a lot of inhalation. In general, the sound absorption rate is as high as 90% or more, is to prevent noise interference;
4, high insulation: glass fiber can be high temperature, good mechanical, and high chemical stability, is the best insulating material;
5, high corrosion resistance: glass fiber is not afraid of strong acid, alkali, for a long time will not reduce its functional characteristics;
6, good recovery: glass fiber contains numerous fixed cavitation, excellent recovery. Not afraid of any shock vibration, tensile strength are more than 1.0kg.
7, low moisture absorption: moisture absorption rate is usually close to zero.
8, light weight and soft: Compared with other insulation materials, glass fiber needle felt the lightest and most soft, if installed in the machine, can reduce the weight and vibration load.
9, the construction of simple: size can be cut according to customers.
Glass fiber needle felt can be used in the automotive industry in the sound insulation, sound absorption, shock absorption, flame retardant, mainly used in the field of industrial filtration; high temperature flue gas filtration; glass fiber needle felt is widely used in carbon black, metal, chemical, incineration and other industries of the flue gas purification and dust recovery of various bags of dust.1, for a variety of heat (coal, electricity, oil, gas) high temperature equipment, central air conditioning pipe insulation;2, for a variety of insulation, fireproof materials;3, for special occasions, sealing, sound absorption, filtration and insulation materials;4, for a variety of heat transfer, heat storage device insulation;5, for cars, boats, aircraft and other parts for the sound insulation, insulation, heat;6, the car, motorcycle muffler core sound insulation and engine silencer;7, color steel and wood structure housing sandwich layer spacing heat insulation;8, heat, chemical pipeline insulation, thermal insulation effect is better than the general insulation materials;9, air conditioning, refrigerators, microwave ovens, dishwashers and other household electrical appliances wall insulation insulation;10, need insulation, heat insulation, fire, sound absorption, insulation of other occasions
Widely used in electromechanical, chemical, construction, transportation, automotive and other industries sandwich insulation and silencer systems, and for insulation and fireproof materials.
